On the March 17th broadcast of KBS 2TV's "Happy Together", guests Jun Hyun Mu and Park Hwi Soon performed a parody of TVXQ's "Keep Your Head Down". As fans may already know, the choreography for this track was created in part by Yunho and Changmin themselves to be as aggressive and powerful as possible. However, this parody was anything but that - in fact, Jun Hyun Mu and Park Hwi Soon drew laughs from the cast for their overexaggerated gestures and frequent pushing and shoving. Towards the end, Park Hwi Soon grabbed Jun Hyun Mu's head and pretended to "pull" him down. Check out the clip below! Their rehearsal video.
